Patented June 7, 1938 UNITED STATES PATENT OFFICE 17 Claims.

The invention aims to provide a new and improved means for mounting a telescopic sight upon a rifle in such manner that said sight may be quickly and easily attached and removed, will occupy a relatively low position on the rifle, will become automatically alined when applied, will require no side supports and when removed will leave the top of the rifle cleagjor the ordinary rear sight.

With the foregoing and minor objects in view, the invention resides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the accompanying drawing.

Fig. 1 is a side elevation showing a portion of a rifle equipped with the improved mounting means for a telescopic sight.

Fig. 2 is a top plan view of the sight mount, part of it broken away and in section.

Fig. 3 is an enlarged side elevation of the mount engaged with the rifle, portions of the latter being in section.

Fig. 4 is a longitudinal sectional view on line 4-l of Fig. 2.

Fig. 5 is a transverse sectional view on line 5-45 of Fig. 3.

Fig. 6 is a transverse sectional view on line 66 of Fig. 3.

A preferred construction has been illustrated and will be rather specifically described, with the understanding however, that within the scope of the invention as claimed, variations may be made.

The receiver 6 of the rifle is provided with the longitudinal loading recess 1 opening through its upper side. I form the front end wall of this recess 7 with a shallow socket 8 which is preferably about hemispherical, said socket opening rearwardly. In the rear end wall of the recess 1, I form a cavity 9 which opens both forwardly and through the upper side of the receiver G, and at opposite sides of said cavity 9, I form threaded openings It! in the receiver. No other variations in the rifle construction are necessary to attach a telescopic sight H thereto with the aid of the present invention.

I provide a horizontally elongated sight-mounting member l2 upon which the sight l I is secured by curved clamps l3, said clamps being fastened upon the end portions of the mounting member 12, by screws or the like M. The front end of the member or body 12 is provided with a forwardly projecting stud l5 which is preferably about hemispherical for snug reception in the socket 8. The rear end of the body I2 is provided with a downwardly projecting lug l6 for snug reception in the cavity 9, and two attaching screws ll are suitably swiveled in said rear end of said body l2, for reception in the threaded openings l0, loss of said screws being prevented by providing them with stop collars or shoulders l8 and by threading stop screws l9 into the rear end of the body l2, the parts l8 and I9 being normally spaced apart such a distance that either screw ll may be entirely disengaged from the threaded opening l0 before the other of the screws ll is started from its respective opening, thus obviating injury to screw threads which would inevitably result if no space were allowed between 18 and I9, necessitating partial unscrewing of one screw, then partial unscrewing of the other, and so on until both screws were disengaged from the openings.

The stud I5 is preferably formed by the front end of a cylindrical pin 20 which is tightly slidable in a bore 2| in the front portion of the body l2, said pin abutting the front end of a screw 22 which is forwardly threaded into said bore. After initially adjusting the device to the gun, it is seldom necessary to touch the screw 22, but if any looseness should occur, said screw may be tightened to force the pin 20 forwardly sulficiently to overcome such looseness. To insure tight fitting of parts when the screws I! are tightened, I bevel the rear end of the lug I6 as shown at 23 and similarly bevel the contacting wall 24 of the cavity 9. After inserting the front portion of the body l2 partially in the recess 9 and engaging its stud IS with the socket l8, and downwardly swinging the rear end of said body, the screws ll may be threaded into place, and during the final tightening of these screws, the b-evels 23 and 24 act as cam surfaces to forwardly force the body l2, thus holding the stud l5 engaged with the socket 8 with extreme tightness, overcoming any vibration and inaccuracies.

The body I2 is preferably of the general shape shown, with its intermediate portion somewhat narrower than its end portions. The entire body is longitudinally channeled in its upper side as shown at 25, and machined seats 26 are employed for the telescopic sight ll, said seats coacting with the clamps or the like l3 in tightly holding said sight. Upon its lower side, the intermediate portion of the body l2 is preferably of substantially V-shape. At the rear end of the body, the latter is of the shape shown in Fig. 5, and the lower side of said body, at the front end thereof, may Well be provided with a longitudinal boss 27 in which a portion of the bore 2| is formed. The upper side of the body is preferably beveled at its longitudinal edge portions so as to not interfere with the ends 28 of the straps or the like l3. At its rear extremity, the body i2 is preferably provided with a T-head 29 formed integrally therewith, the attaching screws I! being rotatably mounted in the ends of this T- head and the lug I6 being integral with the lower side of said T-head.

To attach the device, it is simply necessary to engage the stud l5 with the socket 8 and drive the screws ll tightly into the openings I 0, and by a reversal of these operations, the mount may be removed with equal ease. The telescope sight I I may remain engaged with the mount I2 to be applied and removed bodily with the latter and it will be observed that the construction is such as to insure proper alinement when attaching the mount to the gun. Moreover, the sight will then occupy a relatively low position and will be properly mounted without the necessity of any side arms or the like. The amount is of course sufficiently high to prevent it from interfering with loading, it being customary with telescope-equipped guns to single-load by hand instead of using a clip carrying several rounds. When the mount and the sight are detached, the entire upper portion of the gun is left unobstructed for use of the usual sight.

Excellent results have been attained from the construction shown and described and it is therefore preferably followed. However, within the scope of the invention as claimed, variations may be made, as above stated.
